This certification is for cables that support 4K/UHD and HDR (High Dynamic Range) videos. Cables with Premium high-speed also undergo testing to verify their ability to handle the complete 18Gbps bandwidth while also undergoing an EMI test to ensure they minimize any interference with wireless signals. These cables require a proprietary anti-counterfeiting label on each product. Want to verify the authenticity of the cable?
